AUTOMATIC STUFF-BOX FOB PAPER-MACHINES.

Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed December 81, 1918. Serial 110. 808,789;

To all whom it may concern:

Be it known that I, WILLIAM P. Framer, a citizen of the United States, and a resident of Hudson Falls, in the county of. Washingfor regulatlng the flow of the stock withv reference to the speed at which the paper machine is driven.

Still another object of the invention is to provide means to return the stock to the chest before it reaches the float.

Additional objects of the invention will appear in the following specification in which the preferred form of my invention is described. a

In the drawings similar reference characters refer to similar parts in all theviews in which Figure 1 is a view showing how my stuff box may be used in a paper making machine;

Fig. 2 is a sectional view on the line 22 of Y Fig. 1; Fig. 3 is a plan view of the stufl box;

Fig. 4 is an enlarged sectional view on. the

line 44 of Fig. 3; and Fig. 5 is an enlarged sectional view on the line 55 of Fig. 3.

By referring to the drawings it will be seen that the stock is forced up in the pipe 10 into a compartment 11 in the casin 12, this compartment 11 being separated rom the compartment 13 by a partition 14, the compartment 11 also being separated from the return passage 15 by the partition-16. The partition 14 is disposedlongitudinally of the casing 12 and the partition 16 is disposed transversely of the casing-.12 from the 'tion of the valve member 40 being securedto the flange 42 of the yoke 38. To this yoke .38 there is secured a rod 43 which passes through an opening 44 in a platform 45, the 1 platform 45 being supported by the rods 46 above the top of the casing 12. The upper portion of the rod 43 is threaded at 47 and this'threaded portion of the rod 43 is dis- .sppe' th g n pem g- La.bra ket 4,8, '1

partition 14 to an outer wall of" the casing. In the partition 16 there is an openingl? which is normally closed by a valve 18, this .valve 18 being disposed for moving in guide- .ways, 19 and having a slotted arm 20 in which is disposed a crank 21 on a shaft22, thisshaft 22 being journaled in bearing's 2 3 and 24 in a wall of the casing 12 and in the 22 1 9944.- .Will-;be. ad; $99t iattl} flange 37, at the sides 0 the nut 36?. By this means it is possible to.

shaft 22 may be rotatedby the hand-wheel,-

24 at the outer side of the casing 12, which, with the crank 21 andthe slotted-arm 20, serves as a means to raise or lower the valve 18 as may be desired. When the valve 18 is raised, the stock, which flows up in the pipe 10 to the compartment 11, will pass through this opening 17 tothe return passage 15 and back through the pipe 25 to the stock chest which is not shown in the drawings.

When the stock is to be used in the paper machine, the valve 18 is lowered to close the opening 17. The stock will then accumulate in the compartment 11 and flow over the top of the partition 14 which is lower than'the top of the partition 16. The stock will then accumulate in the compartment 13. This compartment 13 is provided with two out lets'26 and 27, the outlet 26 being located in thepa'rtition 14 and affording communication between the compartment 13 and the return passage 15. The outlet 27 is located in an outer wall of the casing 12 and serves to direct the stock to the mixing box 28 .where the stock is mixed with water, the stock mixed with water passing to the pump 29 from which it is forced through the pipe 30 to the screen 31 and through the screen compartment 31 to the head box 32, from which the stock is fed to the wire screen in the ens-- tomary manner. In the partition 14 at the sides of the outlet 26 there are guideways 33 in which a valve member 34 is disposed, this valve member 34 having an orifice 35, in which is disposed a bolt 36, the bolt 36 also -passing through a slot in a flange 37 on a yoke 38, a collar 36 being disposed on the said bolt 36 and being held against the he slot the-rein by adjust the position of the valve member 34 relatively to the. yoke 38. At the sides of the 'outlet 27 there are guideways 39 in which a valve member 40 is adapted tomove. The

valve member 40 has an opening 41 adapted;-

to register with the outlet 27, the upper porthe bracket 48 being secured to the top of the platform 45. Meshing with the thread 47 on the rod 43 above and below the bracket 48 there are wheels 49, it being possible to turn these wheels 49 home against the bracket 48 to hold the rod 43 and the yoke 38 in adjusted position. As has been stated, it is possible to adjust the valve member 34 relativelyto the yoke 38 and the valve member 40. When the adjustment has been made and the screw has been turned home, it will be seen that by raising the rod 43 and the yoke 38, that the valve member 34 will be moved upwardly relatively to the outlet 26 to expose a greater area between the bottom of the valve member 34 and the bottom of the outlet 26. When the yoke 38 has been raised to move the valve member 34 upwardly in the manner described, it will raise the valve member 40 so that the portion of the valve member 40 below the opening 41] in the valve member will be raised to cover a greater portion of the area of the outlet 27 When the outlet passage to the mixing box is increased in area, the outlet 26 to the return passage 15 decreased in area, while when the outzedh the return passage 15 is increased in rea the passage to the mixing box is decreased-in er a The exposed areas of the outlets 26 and 27 re adjusted for the manufacture of difleren weights of paper and as may be necess when there is a change of speed in t e operation of the paper making machin.

In the operation o the machine, the stock will flow, as has be'n stated, into the compartment 11, and der normal conditions, it will not serve to raise the float, but when the stock becomesthick or the throw of the pump increases, it raises the float. To this float there is secured a sleeve 51 in which is disposed a rod 52, the rod 52 being held in the sleeve 51 by the set screw 53. The rod 52 passes through an opening 54 in the table 45 and to this rod 52 there are secured two levers 55 and 56. lhe lever 55 is fulcrumed on a bracket 57 mounted on the table 45, and the lever 56 fulcrumed on a bracket 58 mounted on the table 45. To the arm 59 of the lever 55 there are secured rods 60, these rods 60 passing through an opening in the table 45 and being secured to the arms 61 which are fulcrumed at 62 to the brackets 63, the brackets 63 being secured to the partition 14 at the sides of the outlet 26. To the arms 61 there is secured a valve 64 for closing or partially closing the outlet 26. To the arm 65 of the lever 56 there are secured rods 66, these rods 66. being articulated to arms 67, pivoted at 68 to the brackets 69, the brackets 69 being secured at each side of the outlet 27 to the outer side of the casing 12. 'To the arms 67 there is secured a valve 70. In the operation of the valve 70 the valve moves above the outlet 27 to expose the outlet, while in the operation of the valve 64, the valve 64 moves below the outlet 26 to expose the "outlet. It will, therefore, be seen that-when the stock becomes thick or the throw of the pump increases beyond normal, it will raise the float 50 and by means of the levers described, will press on the rods 60 and 66 to expose a greater area of the outlet 26 and to close or partially close the outlet 27. lin'this way the even flow of the stock may be maintained under all conditions.

Having thus described my invention ll claim as-new and desire to secure by Letters Patent':v
